The equation of a circle centred at point (m,n) and radius r is given by
<span>(x-m)² + (y-n)² = r²
</span>-------------------------------------------------------------
Centre = (4,3)
radius = 5
Equation:
(x - 4)² + (y - 3)² = 5²
⇒ x² - 8x + 16 + y² - 6y + 9 = 25
⇒ x² + y² - 8x - 6y + 25 = 25
⇒ x² + y² - 8x - 6y = 0
The equation of the circle is x² + y² - 8x - 6y = 0
Hope it helps!
Answer:
4
Step-by-step explanation:
I'm pretty sure theres a graph to this so....
The given parabolic graph of quadratic function
To find:What is F(6) for the quadratic function
Solution:We have given graph of quadratic function
there is a different value for Y and a different value for X
For f(6)
here X=6, need to find graph of quadratic function
X=6
f(6)=4
Y=4
Your welcome :)
50 is not a perfect square because it doesn’t have a square root.

Answer:
77
Step-by-step explanation:
it is the same angle from one side and theother
Answer:
25 ft
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 20 ^2 = x^2
225+400= x^2
625 = x^2
Take the square root of each side
sqrt(625) = sqrt(x^2)
25 = x
